       简单：该组件直接出现在所查看电路中的次数。

      <!-- The distinction between "Unique" and "Recursive" is easiest to explain by considering the 4:1 multiplexer built using three 2:1 multiplexers as in the <a href="../subcirc/sub-using.html">Using subcircuits</a> section. The 2:1 multiplexer contains two AND gates (and the 4:1 circuit includes none), so the "Unique" count of AND gates would be 2; but if you were to build the 4:1 multiplexer using this diagram, you would actually need 2 AND gates for each of the three 2:1 multiplexers, so the "Recursive" count is 6. -->
      “唯一”和“递归”之间的区别最容易解释，通过考虑使用三个 2:1 多路复用器构建的 4:1 多路复用器，如
      <a href="../subcirc/sub-using.html">
       使用子电路
      </a>
      部分。 2:1 多路复用器包含两个 AND 门（4:1 电路不包含任何 AND 门），因此 AND 门的“唯一”计数将为 2； 但如果您要使用此图构建 4:1 多路复用器，则实际上三个 2:1 多路复用器中的每一个都需要 2 个与门，因此“递归”计数为 6。
